The building is great, there is a pool and gym and even table for tennis. Also there is a quiet public space that can be used as coworking. Not too far there is a big shopping center "Terminal 21 Rama 3". The apartment is on 30-th floor with great view on the city. The host was nice and tried to help with any questions.
Among the shortcomings, I can point out that there was smell in the apartment when we arrived. The floor was little bit dirty and there was nothing for living (soap, dish detergent, toilet paper, etc). Not a big problem but be ready. Also there is open space bar near the building. When we lived there, every day there was a live music until 2:00 am. Can be a problem if you have issues with sleeping. But the biggest problem for us were cockroaches. The host bought cockroach repellent that reduced amount of them but every day we saw at least a few anyway.
Overall impression of the apartment was mixed.
